A The mold illustrated in the drawingsis a vertical mold which, withoutlimitation thereto, is

particularly useful for casting slabs of copperand its alloys. 4

Referring to the drawings, the mold illustrated comprises a fixed moldpart A and a complementary mold part B, the two being connected at oneside-for relative swinging about the axial lineof the spaced verticallyaligned pivot pins l (Figs. 1 and 2) and being adapted a mannerhereinafter explained. i

As illustrated (see particularly Figs. 1, 2 and 5), the mold part Acomprises a vertical, longitudinally extending, plate-like member 3,.hereedge flanges 5 or 9. I Each of the ribs 21 ,at the web. integrallysecured as, for example, by welding or casting,to each of the verticaledges of the web 3 is a vertical flange "5- projecting from oppositefaces of the web soas to forma member which has approximately the shapeofan I-beam in transverse cross-section. .The web 3 and flanges 5 of themold part A at their lower ends are shown integrally joined bywelding'or casting to'a'base I for supporting the mold and securing itto a suitable-support.

The mold part B also comprisesgya vertical web a, which in this case isintegrally joined with edge flanges 9 to give the part8 a CI'OSS'.sectional shape approximating that of a channel-iron. e

As illustrated, detachably secured to the inner face of the web '3 ofeach mold part A and B is a plate-like member H defining a face of themold chamber. -Th members IIv are shownas secured to the webs 3 adjacentthe edges of the latter by vertical rows of bolts l3, 9. horizontal rowof bolts l5 at the top of the mold, and a horizontal row of bolts H atthe bottom of the mold. a

Opposite the plates it each of the webs 3 ad jacent its upper and lowerend is provided witha transverse stiffening rib 21 (Figs. 1, 4 and 5),these ribs being integrally formed, by welding or otherwise, with theweb 3 and edge flanges 5 or 9. As shown, the ribs 2| are vin theform ofchannel-irons the flanges of which are in-. tegral with the web 3. Atabout the midpoint of the length of each mold part A and B is atransverse partition rib 23 in the form of a plate integral with the web3 and edge flanges 5 or 9, and extending between this rib 23 and theribs 21 are vertical ribs 25 also in the form of chan nel-ironsintegrally joined to the web 3 and likewise to the rib 23 and ribs 2|.The interior spaces of the channels formed bythe ribs 2| and 25 are incommunication, as clearly shown by Fig. 4, the rib 23 serving as apartition to divide the channel formed by the upper rib v25 from thelower rib 25. At opposite sides'of' the partition rib 23 andextendingbetween the ribs 25 and the edge flanges'S or 9aretransverseribs 21 also in the. form of channelirons and integrallyjoined with the ribs 25, the webs 3, and

right of the-ribs 25, as viewed inFig s. 1 and 4, communicates with theadjacent rib 25. Ina manner hereinafter explained, the lowerribs' 21 atthe right of the ribs. 25, asviewediin Figs; :1 and 4, of each mold partcommunicate wi'tl'i'fa inafter for convenience of terminology called a66 common inlet connect car ie byih m part A, for water or other coolingmedium, while the upper ribs 21 at the right of the ribs 25 communicate'witha common outlet connection 3| carried by the mold part A.

Interiorly of the cooling medium passages afforded by the channel-shapedribs 2|, each web 3 is provided with perforations 33 (Fig. 4) whichcommunicate'with vertical longitudinal grooves 35 formed on the face ofthe web 3 adjacent the plate These grooves are closed by the plates IIand provide channels for the cooling medium. The water or other coolingmedium from the inlet connection 29, as clearly indicated by the arrowsin Fig. 4, enters the passages formed by the adjacent right hand rib 21and flows downwardly th'rough the communicating channel formed by thelower rib 25 and enters the channel formed by the lower rib 2|. Fromthis latter channel it is distributed by the adjacent perforations 33 tothe channels 35, and flowing upwardly through these channels dischargesthrough the upper perforations 33 into the channel formed by the upperrib 2|, whence it flows downwardly through the upper rib and from therethrough the communicating channel formed by the upper rib 21 at theright of this rib 25 to the outlet or discharge connection 3|. In thisway the plates II, which preferably are formed of good conductingmaterial such as copper, are effectively cooled. The approximate I-beamand channel-iron constructions of the body portions of the mold parts Aand B in conjunction with their stiffening ribs form very rigid supportsfor the plates II, which latter are permitted to expand and contract byreason of the clearance in the bolt holes for the bolts securing theplates to the webs 3, yet without warping on account of the rigidity ofthe stiflened webs .3 against which the plates are tightly held by' theclamping means hereinafter described.

In th'e construction illustrated bars 31 defining the sides of the moldchamber are detachably secured to the edge flanges 5. As shown, thesebars are provided with studs 39 (Figs. 1 and 5) projecting throughperforations 4| in the adjachamber with longitudinal bores 41 for thecooling medium, which construction acts to keep the bars cool and toprevent transfer of heat to the flanges 5 so that the latter will nottendto warp. As shown in Figs. 7 and 8, the upper and lower ends of thebores 41 are closed by plugs 49, and are provided with lateral bores 5|communicating with short lengths ,of pipe 53. These pipes slidablyextend through perforations 55 in the flanges 5 so that the side barsmay be adjusted by use of the washers on the studs 39 in the mannerhereinbefore explained, the upper perforations at least havingconsiderable clearance with the pipes to permit the bars freely toexpand and contract longitudinally. To the outer ends of the pipes 53are secured short lengths of flexible hose 51 leading to pipe nipples 59carried by the edge flanges 5. These nipples place the hose incommunication with the channels formed by the adjacent upper and lowerchannel-shaped ribs 2|, as shown in Fig. 6, so that the cooling mediumfrom the inlet connection 29 may enter the lower ends of the bores 41and flow upwardly and discharge from the upper ends of the bores and becarried off by the outlet connection 3| for the cooling medium.

As illustrated, the bottom of the mold chamber is defined by the uppersurface of a .bar Bl (Fig. 8) carried by the mold part A. This bar,which preferably is of cast iron, is secured against the adjacent sideof the plate H of the mold part A by the bolts H which secure that plateto the adjacent web 3. The bar 6| is of such length as to extend underthe opposite side bars 31, and is adapted to be stronglyforced againstthe lower ends of the latter by screw jacks 63,- which jacks areadjustably screwed into the base 1 of the mold part A and have lock nuts64 to prevent them from accidentally backing off. The clearance aboutthe bolt holes for the bolts permit sufiicient movement of the bar 6| topermit it to be so forced by the jacks 63, and permitslongitudinal'expansion and contraction of the bar,

cent edge flanges 5, and are rigidly clamped to the bars by nuts 43carried by the studs. As illustrated in Fig. 5, a series of washers 45of dif ferent thickness are placed between the nuts 43 and the adjacentside of each flange 5. One or more of these washers, or all of them, maybe placed at the opposite side of the flange so as to lie between theflange and the adjacent bar 31, and by so positioningthem the width ofthe mold chamber may be varied say, for example, by moving either orboth bars 31 to their dotted line positions shown in Fig. 5. So that thewashers 45 may be readily removed and replaced without the necessity ofdetaching the side bars from the edge flanges 5, the washers arepreferably formed with radial slots 46 of width the diametersof thestuds 39, which slots open into the stud receiving bores of the washersto give the latter a U-shape' as shown in Fig. 5 -This constructionprovides a rigid support for the side bars 31, the bars being permittedto expand and contract longitudi nally by reason of the clearancebetween the stud bolts 39 and the walls of the perforations 4|, yet thebars are strongly held against thefianges 5 by the nuts 43 and arestrongly clamped between the plates II to prevent warping of the bars.

As shown, the side bars 31 are provided adjayet the jacks 63 preventwarping of the bar, and, by forcing them against the lower ends of theside bars 31, insures against entrance of metal between the upper faceof the bar 6| andthe ends of the side bars.

The means for pivotally supporting the mold parts A and B is best shownby Figs. 1 to 5. As illustrated, to one of the flanges 5 of the moldpart A are rigidly secured spaced brackets 5.1 which carry thevertically positioned pivot pins herein|beforereferred to. These pinsserve pivotally to secure links 69 to the ends of the brackets, whichlinks, as shown, are of rectangular cross-section (Fig. 4). Preferablythe construction is such that no lateral lost motion exists in thehinged joints so formed, the pins making tight joints with theperforations in the brackets and links which receive them. Rigidlysecured to the flange 9 of the mold part B adjacent the links 69 areblocks 1| having perforations I3 opposite side of the mold. To the edgeflange cent their surfaces defining the sides of the mold 5 of the moldpart A at that side are secured spaced brackets TI to the outer ends ofwhich at 19 are pivotally secured the ends of links 8|, the latterremovably extending through the openings formed by the bifurcatedadjacent ends 83 of the yoke bars 15 and adjustably carrying nutsassaaos ll resting against the outer surfaces of the yoke bars at thoseends so that the yoke bars may be forcibly drawn toward the mold part Ato clamp the mold part B :between it and the yoke bars.

As shown, the mold part B is provided with a' plate 01 beneath each yokebar, the plate being notched to permit the ribs 25 to pass through itand fitting the exterior of those ribs at the outer surface of the web Iand adjacent parts of the edge flanges and being welded thereto or beingotherwise integrally formed with the body of the mold part B. Asillustrated (see Fig.5), the intermediate portion of each yoke bar ischannelshaped in cross-section, the adjacent plate 81 fitting withinthis channel and being pivoted to the yoke bar by a pin 89, the alignedholes 9| in the yoke bars for receiving the .pins being elongated in thedirection of the lengths of the yoke .bars, as shown in Fig. 5, so thatthe mold part 3 may move longitudinally of those bars.

The combined structure for pivotally securing the mold part B to themold part A and for clamping the two together permits the mold part 'Bto adjust itself toward the mold part A and transversely thereof, whileforcing the mold part B to swing around the aligned axes of the pivotpins I. This permits slight variations in the thickness of the sidebars31 and bottom bar I so that the thickness of the casting may be varied,and permits the surfaces of the plates H defining the faces of the moldchamber to'be finished from time to time and takes care of discrepanciesin manufacture of the parts.

As illustrated (see Figs. 1, '3 and 4), the cute side of the edge flange5 of the mold part A opposite the flange 5 thereof which carries thealigned pivot pins I carries a bar which provides a lug 93 projectingtoward the mold part B. The adjacent edge flange 9 of the mold part Bcarries a roller 95 adapted to ride on the upper surface of the lug 93.In this way the mold part B is brought into proper position in avertical direction with the mold part A to take care of wear anddiscrepancies in manufacture in the hinged support for the mold part B.The lug 93, as clearly shown in Fig. 4, has a slight clearance with theadjacent web flange 5 of the mold part B, and this clearance and thesliding contact of the plate ll of the mold part B with the side bars 31permit any slight transverse sliding of the mold part B relative to themold part A necessary to bring-the two properly together.

The water conducting means between the water inlet and outletconnections 29 and ii of the mold parts A and B is such as to permit theabove described relative swinging of these parts and their relativemovement transverse to the hinge axis. As this water conducting meansforms thesubject of a further divisional application based on the sameparent application of whichthe present application is a. division itneed not-be described herein with any more particularity than isnecessary to explain how it it coacts with the hinge and clamping meansabove described. Briefly, to the flanges I and 8 of the mold parts A andB are bolted at 98 and I" (Fig. 2) pipe sections 9! and Ill,respectively, the free ends of these pipe sections being verticallyspaced from each other and horizontally overlapping, as clearlyillustrated in Fig. 2. These overlapping free ends in each instance aresection 99, which joint is connected to the pipe section "I by alongitudinally extensible and laterally yieldable conduit (not shown)approximately coaxial with the hinge pin and also within the housingI01. Each pipe section 99 and l3l 'in its base is provided with anopening in combase with an opening I39 in communication with an alignedopening ill in the flange 9, this opening I31 being in communicationwith the passage formed by the adjacent hollow rib 21.
